2019-08-09 17:07:41 -0500 | marked best answer | Serial Connection to Hokuyo from Master Hi, I am currently getting the error: Initially, after encountering this problem, I was able to resolve it by adding myself to the dialout list as suggested: https://answers.ros.org/question/2866... I was able to view the data from the Hokuyo after doing this. I am now trying to access the Hokuyo from a different machine. On the drone (where the Hokuyo is connected), I changed ROS_MASTER_URI and ROS_IP to match the PC. On the PC, I then ran: I am able to run '$ rostopic list' correctly. However, after typing '$ rosrun urg_node urg_node', I receive the error mentioned above. Any help is greatly appreciated. Thanks, Justin |
